documentation: initial script to merge header comments and the wiki. This is a work-in-progress, but the idea is it can convert between our wiki and the SDL header's doxygen comments, so we can attempt to keep them in sync. This might be a fool's errand, but I'm optimistic it'll work enough that we can clean up little issues as we go, as long as we have some discipline about how we write documentation. If nothing else, it's going to result in a solid spring-cleaning of both the wiki and the headers!
